- It's a great way to use up leftover corned beef and roasted potatoes.
- Homemade hash is full of fresh ingredients - no canned hash here!

Ingredient Notes
- Corned beef brisket: Leftovers are ideal for making hash. Alternatively, you can buy a thick, unsliced piece of cooked corned beef from the supermarket deli and cut it into cubes.
- Potatoes: I love using baby potatoes because of their creamy texture. Both red and white varieties are delicious. For larger potatoes, cut them into 1-inch pieces. Leftover roasted potatoes also work well.

How to Make Corned Beef Hash
Step 1: Toss the potatoes with oil and season with salt and pepper. Transfer to a preheated cast-iron skillet and roast at 400℉ for 20 minutes until fork-tender, stirring after 10 minutes. Transfer them to a plate.
Step 2: Heat oil in the same skillet over medium heat. Add the peppers and onions, season with black pepper, and cook for 8-10 minutes until softened and slightly caramelized.
Step 3: Add the corned beef and cook for another 8-10 minutes.
Step 4: Stir in the potatoes and cook until warmed through. Taste and adjust seasoning to taste.
Expert Tips
- Use a preheated cast-iron skillet to promote browning and create caramelized edges for extra flavor.
- Roasting the potatoes in the oven helps them to caramelize while cooking evenly throughout.
- Add salt sparingly since corned beef is high in sodium.
Serving Suggestions
- Top with a poached or sunny-side-up egg for a hearty breakfast.
- Add to a brunch spread with scrambled eggs and fruit salad with anise simple syrup.
- Serve as a one-dish dinner.
- Serve with brown mustard or Thousand Island dressing for a Reuben vibe.
- Use leftovers to make a corned beef hash frittata.
Recipe FAQs
Canned corned beef is a pre-cooked, salted beef brisket that can be used as a convenient substitute. Since it is high in sodium, add salt sparingly (or omit salt altogether) when making hash.
Hash keeps well in the fridge for up to four days. It can be prepared in advance and reheated in a skillet over medium heat.
